Two views:

• Active — every sandbox still alive (within TTL, not deleted)

• History — all sandboxes ever, paginated, newest first

Click any sandbox to drill into its runs: timing, exit code, and errors per execution.

No setup, no external dependencies — it's served straight from Petri and works fully self-hosted/offline. Open http://localhost:8000/dashboard and it's there.

This builds on v0.9's observability (the run model + metrics) — now you can actually see it, not just query it.
